A cutting equipment using a mixed gas of hydrogen and oxygen that has a cooling part within a holder to prevent deformation of the equipment, improves mobility of the holder to cut a matrix accurately, and can use an existing fuel as well as the mixed gas of hydrogen and oxygen is provided. A cutting equipment using a mixed gas of hydrogen and oxygen comprises: an exclusive hydrogen/oxygen mixed gas nozzle(21) for exhausting a hydrogen/oxygen mixed gas; an exclusive hydrogen/oxygen mixed gas holder(12) which holds the nozzle in the state that the nozzle is mounted on the holder, and in which a gas inflow path is formed; a cooling part installed within the holder to prevent deformation of the holder and the nozzle due to deterioration and circulation-cool the holder and the nozzle; a moving screw(24) for moving the holder forward and backward, side to side, and up and down; and a hydrogen/oxygen mixed gas supply part(11) for supplying the hydrogen/oxygen mixed gas to the cutting equipment. The cutting equipment further comprises a hydrogen/oxygen mixed gas generator for generating the hydrogen/oxygen mixed gas, and a backfire prevention machine(20) installed above the holder to prevent backfire generated within the cutting equipment. |
